Lenovo 720s Webcam not recognized

Hello everyone!
I’m having truobles with the integrated webcam of my Lenovo 720S-14klb.
Trying with Zoom, Skype and Hangouts most of the times, the webcam is not recognized, but only few times, it sorpresivelly woks.
I have Fedora 30, kernel 5.5.16

Some info:

$ dmesg | grep video
[    5.259390] videodev: Linux video capture interface: v2.00
[    5.370747] uvcvideo: Found UVC 1.00 device EasyCamera (13d3:5621)
[    5.375078] uvcvideo: Failed to initialize entity for entity 6
[    5.375079] uvcvideo: Failed to register entities (-22).

Part of:

$ lsmod

$ modinfo uvcvideo

version:        1.1.1
license:        GPL

And “sudo modprobe uvcvideo”, doesn’t show any error
I’d tried removing with modprobe -r uvcvideo & then modprobe uvcvideo again, and nothing.

I also try with gdm, lxdm, and kdm

Any ideas?
Pleanse help me!

Thanks!Preformatted text

Hi @dieguito, i had same issues on the same terms in the past.  Please try 32-th release.  Fedora-30 is EOL in one month.
